Identification and Analysis of Off-grid Energy Sources Used at the Household Scale in Lubumbashi, DR Congo

Banza Wa Banza Bonaventure and Mbangu Tshingej Nene

Background and Objective: In Lubumbashi the electrical service is characterized by frequent load shedding, longer and unplanned. To overcome this situation, population of Lubumbashi is forced to resort to alternative energy sources. The main objective of this study was to identify and analyze the different energy sources used in household scale in Lubumbashi. Materials and Methods: A total of 5270 households were surveyed in the 26 districts grouped into 7 municipalities. Data from household surveys have been subjected to one-way analysis of variance (ANOVA) to highlight the differences between averages of municipalities. In addition, a Tukey post-hoc test was applied to determine the difference between the means for the result with a significant difference (p<0.05). R 2.15 and past software were used for statistical analysis. Results: The results revealed 2 main sources of energy used for cooking, 4 for lighting and 3 as alternative sources of electricity. In the case of cooking, households mainly prefer charcoal than wood heaters. Only some households of outlying districts still use wood for cooking. These preferred sources however result in multiple negative consequences for both human health and the environment. Regarding the sources of energy for lighting, candles are the most preferred because of easy accessibility while producing poor quality light. In case of load shedding or lack of electricity, some households are implementing alternative sources such as the generator and solar panels. Indeed, the use of these sources varies from one to another, with a higher frequency of generator use. Conclusion: In this context, programs that would target improving and increasing access to sustainable and clean energy, should take account of geographical disparities due to population growth and sprawl of Lubumbashi.
